My favorite fight is the one when Naruto and Sasuke use the rasengan and chidori together. I like that fight because it gave me hope to see Sasuke back to Konoha. Sakura tried to kill him but didn't succeed and Naruto came just in time to help Kakashi and Sakura. To me, it was a fight out of the ordinary. I gotta admit my favourite part of that fight is when Naruto and Sasuke get in a sort of 'peaceful' place. They talk and Naruto keeps being positive. I can watch and rewatch the same episode and I will always enjoy it. During episode 215

My favorite fight would be Sasuke vs Killer Bee. The fight showed us how cool was Killer Bee and I finally got to see Sasuke getting the crap out of him beaten, which he deserved since a long time ago.

This fight is the most emotional fight i think in the series. This fight also shows how much Jiraiya loved Naruto. I was nearly in tears when Jiraiya died. Jiraiya is my favorite character in all of Naruto. You'll never be forgotten pervy sage

the best fight was in my opion the fight between naruto and the pains because the killed jiraya and destroying the village with the whole population and can just be ended when naruto fight against them
you can also found this fight on
www.crunchyroll.com, season 8, episodes 167

Team ten plus Kakashi vs. Hidan and Kakuzu!
This is the best fight ever! Shikamaru shows off his genius, Kakashi is in it, the animation is great, it takes place in a sweet forest of dead trees, its a fight against TWO Akatsuki members, one of which is immortal and the other has five lives, AND YET TEAM TEN STILL WINS!!! All in rememberence of their beloved team leader..... and then Naruto comes and busts out his sweet new Rasengan!!!
How the heck can a fight get any better than that!?!? :)

Well, if you ask me there has been one particular fight in were the outcome was much more obscured. The fight were Shikamaru's Team (lead by Kakashi) seeks vengeance for the murder of their teacher is by far in my opinion one of the best in the series. Shikamaru's resolve unbelievable, he was able to see all out comes and possibilities. Hidan and Kakuzu never stood a chance.

Reason: This was really first time we see a new badass ninja (B) and he's fighting the newly awaken Sasuke. Words can not express the epicness of this fight! Pure awesomeness. The best about this fight is that Sasuke get his ass handed to him. It's really hard to pick your favorite it was either this or the Itachi fight. I really hope I win.

My favourite fight is killer bee vs hebi, mostly because of the great sword fighting and fluidity of the fight but also because im not the biggest sasuke fan and this fight saw him get not just beat for his cockyness but nearly killed and then inevitably completely tricked too showing how good kiler bee is in the process. It also introduced the great character of killer bee.

The battle is just filled with intense emotions and battle scenes. You get to see how much Naruto has grown and how he still has much more room to grow. This is where Naruto's greatest lesson is learned: Receiving pain and learning to deal with it without continuing the cycle of hatred which he had promised Jiraiya he would stop. A lot of things happen throughout the battle such as with Hinata, Naruto nearly losing control of the Kyuubi, finding out who is father is, and learning the story of how Pein came about. This is also the battle where Naruto was finally completely acknowledged as the Hero of the Hidden Leaf Village.
Not to mention Naruto's entrance was so freaking awesome.

Episode 249 thank you
After 16 years naruto finally meets his mom and gets to learn the truth behind the nine tails attack and how naruto's parents gave their lives to save naruto and entrusting naruto with the nine tails and then the fight with the nine tails with some help of his mom

Minato vs Obito. Hidden Leaf vs The Nine Tails. This was a defining moment in the series in terms of battles for me. Watching Minato use his seals to transport the blast away, watching Obito cause havok in the village, and finally getting to see The Fourth Hokage use his skills...It is too beautiful!
